GENERAL PROVISIONS RELATING TO THE TRUSTEE

The appointment of any successor Trustee, provisions governing resignation and compensation of the Trustee, and the general rules governing the relationships of the Trustee and ZionSolutions and any third parties are as follows:

3.1          Designation and Qualification of Successor Trustees.  At any time during the term of the Trust Agreements, ZionSolutions shall have the right, with respect to the Trust, to remove the Trustee acting under the Trust Agreement and appoint another qualified entity as a successor trustee upon 60  days’ notice in writing to the Trustee, or upon such shorter notice as may be acceptable to the Trustee.  Any Trustee shall have the right to resign at any time upon 60 days’ notice in writing to ZionSolutions and upon such resignation ZionSolutions shall appoint another qualified entity as a successor Trustee for the Trust.

Any successor Trustee shall qualify by a duly acknowledged acceptance of the Trust Agreement, the Trust created hereunder and these Backup NDT Terms, delivered to ZionSolutions.  Upon acceptance of such appointment by the successor Trustee, the Trustee shall transfer to such successor Trustee the Disposal Capacity Asset.  Any successor Trustee shall have all the rights, powers, duties and obligations herein granted to the original Trustee.

7

If for any reason ZionSolutions is unable to or does not appoint a successor Trustee within 90 days after the resignation or removal of the Trustee for the Trust as provided above, ZionSolutions,  or the Trustee may apply to a court of competent jurisdiction for the appointment of a successor Trustee.

3.2          Compensation and Reimbursement.  The Trustee shall be entitled to compensation from ZionSolutions at such rates as may be approved in writing from time to time by ZionSolutions.  Subject to the approval of ZionSolutions (which shall not be unreasonably withheld or delayed), the Trustee shall be entitled to be reimbursed from ZionSolutions for out-of-pocket expenses, including, but not limited to, expenses of agents, auditors and counsel, incurred in connection with the administration of such Trust.  ZionSolutions acknowledges that, as part of the Trustee’s compensation, the Trustee will earn interest on balances, including disbursement balances and balances arising from purchase and sale transactions as disclosed in the Trustee’s float policy.  Expenses for which ZionSolutions may reimburse the Trustee also include taxes of any kind whatsoever that may be levied or assessed under existing or future laws of any jurisdiction upon or in respect of the Trust.  The Trustee may take all action necessary to pay for, and settle, Authorized Transactions, including exercising the power to borrow or raise monies from the Trustee in its corporate capacity or an affiliate.  To secure advances made to settle or pay for Authorized Transactions, including payment for securities and disbursements, ZionSolutions grants to the Trustee a first priority security interest in the Trust, all Property therein, all income, substitutions and proceeds, whether now owned or hereafter acquired (the “Collateral”); provided that ZionSolutions does not grant the Trustee a security interest in any securities issued by an affiliate of the Trustee (as defined in Section 23A of the Federal Reserve Act) or in the Disposal Capacity Assets.  The parties intend that as the securities intermediary with respect to the Collateral, the Trustee’s security interest shall automatically be perfected when it attaches.  The Trustee shall be entitled to collect from the Trust sufficient cash for reimbursement and, if such cash is insufficient, dispose of the assets of the Trust to the extent necessary to obtain reimbursement.  To the extent the Trustee advances funds to the Trust for disbursements or to effect the settlement of purchase transactions, the Trustee shall be entitled to collect from the Trust reasonable charges established under the Trustee’s standard overdraft terms, conditions and procedures.

3.3          Transactions With Third Parties.  No person or organization dealing with the Trustee shall be required to inquire into or to investigate its authority for entering into any transaction or to see to the application of the proceeds of any such transaction.

3.4          Financial Statements.  In the event funds are drawn from the Letter of Credit and deposited with the Trust the Trustee shall furnish monthly audited statements for the Trust to ZionSolutions not later than the 15th business day of the following month.  The statements shall show the financial condition of the Trust, including, without limitation, the market value of the assets, and the income and expenses of the Trust for the period since the preceding statement.  Any such statement may be approved by ZionSolutions with respect to the Trust by written notice to the Trustee or by failure to object to such statement within 180 days after the date upon which such statement was delivered to ZionSolutions.  The approval of any such statement shall constitute a full and complete discharge of the Trustee as to all matters set forth in such statement; provided, however, that the foregoing shall not relieve or absolve the Trustee from

any liability associated with a failure to perform its fiduciary responsibilities.  The statements shall be audited upon direction of ZionSolutions by independent certified public accountants, subject to the limitations contained in Section 4.9 hereof.   In providing pricing or other Market Data in connection with this Agreement, the Trustee is authorized to use Data Providers to provide such Market Data.  The Trustee may follow Authorized Instructions in providing pricing or other Market Data, even if such instructions direct the Trustee to override its usual procedures and Market Data sources.  The Trustee shall be entitled to rely without inquiry on all Market Data (and all Authorized Instructions related to Market Data) provided to it, and the Trustee shall not be liable for any Losses incurred as a result of errors or omissions with respect to any Market Data utilized by the Trustee or ZionSolutions hereunder.  Zion Solutions acknowledges that certain pricing or valuation information may be based on calculated amounts rather than actual market transactions and may not reflect actual market values, and that the variance between such calculated amounts and actual market values may be material.  Market Data may be the intellectual property of the Data Providers, which may impose additional terms and conditions upon ZionSolutions’s use of the Market Data.  The additional terms and conditions can be found on the Data Terms Website.

3.5          Tax Returns, Tax Information Returns and Other Reports.  The Trustee shall prepare or cause to be prepared tax information returns and such reports as may be required from time to time for the Trust, and shall provide copies thereof to ZionSolutions in advance of its filing for review.  The Trustee shall provide to ZionSolutions all statements, documents, lists, or other information related to such tax returns and information returns reasonably requested by ZionSolutions.  The Trustee shall also sign all such tax information returns, and the Trustee shall file them or cause them to be filed with the appropriate government agencies.  The Trustee shall cooperate with all requests made by regulatory agencies related to such tax returns and information returns and shall provide copies to ZionSolutions in advance of all information related to such tax returns and information returns submitted by the Trustee to regulatory agencies (unless prohibited by the terms of such request).  Notwithstanding the foregoing, no such notice shall be required in the case of disclosure by the Trustee to any of its regulators.

3.7          Future Orders.  ZionSolutions shall promptly advise the Trustee in writing of the existence of any Future Orders having the effect of imposing new or different responsibilities upon the Trustee under the Trust Agreement or these Backup NDT Terms.

3.8          Appointment of Investment Manager.

(a)           ZionSolutions shall have the right from time to time to appoint and remove one or more Investment Managers for the Trust held under the applicable Trust Agreement and to direct the segregation of any part or all of any such Trust into one or more accounts to be known as “investment manager accounts” and if ZionSolutions does so, it shall appoint an individual, partnership, association, or corporation as Investment Manager to manage the portion of any Trust so segregated, provided, however, that ZionSolutions, its affiliates, and its subsidiaries and persons representing them shall not provide day-to-day management direction of investments or direction on individual investments to either the Trustee or an investment manager.  Written notice of any such appointment and/or removal shall be given to the Trustee and the Investment Manager so appointed.  The appointment, after the date hereof, shall be accomplished using an investment manager agreement signed by ZionSolutions and the Investment Manager.  The Trustee may assume that any investment manager account previously established and the prior appointment of any Investment Manager for that account continues in force until receipt of written notice to the contrary from ZionSolutions.  As long as the Investment Manager is acting, the Investment Manager shall have full authority to direct the acquisition, retention and disposition of the assets from time to time comprising the investment manager account being managed by the Investment Manager, in accordance with Sections 2.5(c), 4.2, 4.3, 4.4 and 4.5 hereof.  Upon the segregation of the assets in accordance with ZionSolutions instructions, the Trustee, as to those assets while so separated, shall be released and relieved of all investment duties, investment responsibilities and investment liabilities normally or statutorily incident to a trustee; provided, however, that the Trustee shall review the transactions in each investment manager account for the purpose of determining whether any assets acquired or any pending asset acquisitions (as to which the Trustee has been given information) are Prohibited Investments as provided in Section 4.3 hereof.  In the event that the Trustee determines as a result of any such review that an investment is a Prohibited Investment as provided in Section 4.3, hereof, then it shall notify ZionSolutions and the applicable Investment Manager within a reasonable period of time after such determination by telephone, with confirmation in writing.  The Trustee shall retain all other fiduciary duties with respect to assets the investment of which is directed by investment managers.

(b)           ZionSolutions hereby agrees to indemnify the Trustee and hold it harmless from any liability or expense incurred without negligence, willful misconduct, recklessness or bad faith on the part of the Trustee, in connection with or arising out of:  (i) any action taken or omitted or any investment or disbursement of any part of the investment manager account made by the Trustee at the direction of the Investment Manager, or (ii) any action taken by the Trustee pursuant to notification of an order

10

issued by an Investment Manager to purchase or sell securities directly to a broker or dealer under a power of attorney.

(c)           To the extent that ZionSolutions notifies the Trustee that any Trust assets are currently not allocated to an investment manager account, to the extent agreed to by the Trustee in writing, the Trustee shall have investment responsibility for such assets until further notice from ZionSolutions, and shall hold, invest and reinvest such assets subject to any investment guidelines issued to it by ZionSolutions, and subject further to the provisions of Sections 4.2 and 4.3 hereof.

3.9          [Intentionally Deleted].

3.10        Certain Duties and Responsibilities of the Trustee.

(a)           In the absence of bad faith on its part, the Trustee may conclusively rely upon certificates or opinions furnished to the Trustee and conforming to the requirements of the Trust Agreement and these Backup NDT Terms; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall have no duty to examine the same to determine whether they conform to the requirements of the Trust Agreement and these Backup NDT Terms unless the representative of the Trustee involved with the certificate in question has actual knowledge of the falsity of any statement made therein.

(b)           In performing its duties under this Agreement, the Trustee shall exercise the same care and diligence that it would devote to its own property in like circumstances.  The duties of the Trustee shall only be those specifically undertaken pursuant to this Agreement.  The Trustee shall not be liable for any action taken by it in good faith and without negligence and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement and may consult with counsel of its own choice (including counsel for ZionSolutions) and shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and without negligence and in accordance with the opinion of such counsel.   ZionSolutions hereby agrees to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence, willful misconduct or bad faith on the part of the Trustee, arising out of or in connection with its entering into this Agreement and carrying out its duties hereunder, including the costs and expenses of defending itself against any claim of liability.  Except as otherwise provided in this Agreement, the Trustee shall be liable for the actions of its nominees and the agents it selects.

The Trustee shall not be responsible or liable for any losses or damages suffered by the Trust arising as a result of the insolvency of any custodian, subtrustee or subcustodian, except to the extent the Trustee was negligent in its selection or continued

11

retention of such entity.  Under no circumstances shall the Trustee be liable for any indirect, consequential, or special damages with respect to its role as Trustee.

3.11        Certain Rights of Trustee.

(a)           ZionSolutions shall notify the Trustee in writing of all Authorized Officers and the rights, powers and duties of each such person or entity.  Any Investment Manager appointed pursuant to Section 3.8 shall notify the Trustee in writing of all persons or entities who are authorized to act on its behalf and the rights, powers and duties of each such person or entity.  The Trustee shall be entitled to deal with any such person or entity identified by ZionSolutions or by an Investment Manager (“Authorized Party” or “Authorized Parties”) until notified otherwise in writing.

(b)           “Authorized Instructions” shall mean (i) all directions to the Trustee from an Authorized Party pursuant to the terms of this Agreement; (ii) all directions by or on behalf of ZionSolutions to the Trustee in its corporate capacity (or any of its affiliates) with respect to contracts for foreign exchange; (iii) all directions by or on behalf of ZionSolutions pursuant to an agreement with Trustee (or any of its affiliates) with respect to benefit disbursement services or information or transactional services provided via a web site sponsored by the Trustee (or any of its affiliates) (e.g., the “Workbench web site”) and (iv) all directions by or on behalf of ZionSolutions pursuant to any other agreement or procedure between Trustee (or any of its affiliates) and ZionSolutions, if such agreement or procedure specifically provides that authorized persons thereunder are deemed to be authorized to give instructions under this Agreement.  Authorized Instructions shall be in writing, transmitted by first class mail, overnight delivery, private courier, facsimile, or shall be an electronic transmission subject to the Trustee’s policies and procedures, other institutional delivery systems or trade matching utilities as directed by an Authorized Party and supported by the Trustee, or other methods agreed upon in writing by ZionSolutions and the Trustee.  The Trustee may, in its discretion, accept oral directions and may require confirmation in writing.  However, where the Trustee acts on an oral direction prior to receipt of a written confirmation, the Trustee shall not be liable if a subsequent written confirmation fails to conform to the oral direction.

(c)           The Trustee shall be fully protected in acting in accordance with all instructions that the Trustee reasonably believes to be Authorized Instructions.

(d)           “Authorized Transactions” shall mean any action or series of actions resulting from Authorized Instructions.

(e)           The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Trust Agreement at the request or direction of ZionSolutions pursuant to the Trust Agreement or these Backup NDT Terms, unless ZionSolutions shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

12

(f)            Notwithstanding anything in this Agreement to the contrary, the Trustee shall not be responsible or liable for its failure to perform under this Agreement or for any losses to the Trust resulting from any event beyond the reasonable control of the Trustee, its agents or subcustodians, including but not limited to nationalization, strikes, expropriation, devaluation, seizure, or similar action by any governmental authority, de facto or de jure; or enactment, promulgation, imposition or enforcement by any such governmental authority of currency restrictions, exchange controls, levies or other charges affecting the Trust’s property; or the breakdown, failure or malfunction of any utilities or telecommunications systems; or any order or regulation of any banking or securities industry including changes in market rules and market conditions affecting the execution or settlement of transactions; or acts of war, terrorism, insurrection or revolution; or acts of God; or any other similar event.  This Section shall survive the termination of this Agreement.

ARTICLE 4:  TRUSTEE’S POWERS

The Trustee shall have, with respect to the Trust Agreement, the following powers, all of which powers are fiduciary powers to be exercised in a fiduciary capacity and in the best interests of the Trust, and which are to be exercised as the Trustee, acting in such fiduciary capacity, in its discretion, shall determine, except that the Trustee shall not act in its discretion but only at the direction of an appointed Investment Manager in the exercise of those powers given in Sections 4.2, 4.3, 4.4 and 4.5 hereof with respect to the acquisition, retention, and disposition of the assets of an investment manager account, which are intended in no way to limit the general powers of the office.  The Subordinated Trustee shall have those powers set forth in an appropriate Subordinated Trust Agreement, which shall not be inconsistent with the material terms of the Trust Agreement or these Backup NDT Terms.

4.1          Payment of or Provision for Expenses of Administration.  The Trustee shall have the power to incur, pay or make provision for any and all charges, taxes, and expenses upon or connected with the Trust Agreement in the discharge of its fiduciary obligations thereunder (and other incidental expenses of the Trust (including legal, accounting, actuarial and trustee expenses)).

4.2          Investment of Trust Fund:  Prudent Investor Standard.

(a)           In the event funds are drawn from the Letter of Credit and deposited with the Trust, and pending any other permissible use of the Trust held under the Trust Agreement, and subject to the limitations provided in Section 4.3 of these Backup NDT Terms, the Trustee shall have the power and authority to invest and reinvest all or any part of the assets of such Trust, including any undistributed income therefrom, in a manner consistent with the “prudent investor” standard as specified in 18 CFR § 35.32(a)(3) of the Federal Energy Regulatory Commission regulations and in such a way as to attempt to achieve reasonable after-tax returns thereon, considering the pattern of

13

cash flow, decommissioning schedule and other such considerations made known to the Trustee by ZionSolutions.  Any investment advisor or other person directing such investments shall adhere to the “prudent investor” standard, as specified in 18 CFR § 35.32(a)(3).

(b)           In the exercise of the power and authority set forth in Section 4.2(a) hereof, the Trustee has the following powers and authority:

(i)            to purchase, receive or subscribe for any securities or other property and to retain in trust such securities or other property;

(ii)           to sell, exchange, convey, transfer, lend, or otherwise dispose of any property held in the Trust and to make any sale by private contract or public auction; and no person dealing with the Trustee shall be bound to see to the application of the purchase money or to inquire into the validity, expediency or propriety of any such sale or other disposition;

(iii)          to vote in person or by proxy any stocks, bonds or other securities held in the Trust;

(iv)          to exercise any rights appurtenant to any such stocks, bonds or other securities for the conversion thereof into other stocks, bonds or securities, or to exercise rights or options to subscribe for or purchase additional stocks, bonds or other securities, and to make any and all necessary payments with respect to any such conversion or exercise, as well as to write options with respect to such stocks and to enter into any transactions in other forms of options with respect to any options which the Trust has outstanding at any time;

(v)           to join in, dissent from or oppose the reorganization, recapitalization, consolidation, sale or merger of corporations or properties of which the Trust may hold stocks, bonds or other securities or in which it may be interested, upon such terms and conditions as deemed wise, to pay any expenses, assessments or subscriptions in connection therewith, and to accept any securities or property, whether or not trustees would be authorized to invest in such securities or property, which may be issued upon any such reorganization, recapitalization, consolidation, sale or merger and thereafter to hold the same. To the extent that any securities that are accepted are attributable to an investment manager account, the provisions of Section 3.8(a) apply with respect to Trustee review for Prohibited Investments under Section 4.3 and notification of ZionSolutions and the applicable Investment Manager;

(vi)          to enter into any type of contract with any insurance company or companies, either for the purposes of investment or otherwise; provided that no insurance company dealing with the Trustee shall be considered to be a party to the Trust Agreement and these Backup NDT Terms and shall only be bound by and held accountable to the extent of its contract with the Trustee. Except as

14

otherwise provided by any contract, the insurance company need only look to the Trustee with regard to any instructions issued and shall make disbursements or payments to any person, including the Trustee, as shall be directed by the Trustee.  Where applicable, the Trustee shall be the sole owner of any and all insurance policies or contracts issued.  Such contracts or policies, unless otherwise determined, shall be held as an asset of the Trust for safekeeping or custodian purposes only;

(vii)         to invest assets of the Trust in foreign and domestic futures contracts, options on futures contracts, options contracts, swaps, short sales and other derivative investments, and, in connection with such investments, to transfer assets of the Trust to brokers or other third parties as margin or collateral at the direction of the Investment Manager; provided, however, that the Investment Manager and Trustee shall have first entered into an appropriate account agreement with such broker or third party.  Notwithstanding anything to the contrary contained in the Trust Agreement or these Backup NDT Terms, the Trustee shall have no custodial responsibility for any assets so transferred;

(viii)        to invest in any collective, common or pooled Trust operated or maintained exclusively for the commingling and collective investment of monies or other assets including any such fund operated or maintained by the Trustee or its affiliates.  Notwithstanding the provisions of this Agreement which place restrictions upon the actions of the Trustee or an Investment Manager, to the extent monies or other assets are utilized to acquire units of any collective trust, the terms of the collective trust indenture shall solely govern the investment duties, responsibilities and powers of the trustee of such collective trust and, to the extent required by law, such terms, responsibilities and powers shall be incorporated herein by reference and shall be part of this Agreement.  For purposes of valuation, the value of the interest maintained by the Fund in such collective trust shall be the fair market value of the collective fund units held, determined in accordance with generally recognized valuation procedures.  ZionSolutions expressly understands and agrees that any such collective fund may provide for the lending of its securities by the collective fund trustee and that such collective fund’s trustee will receive compensation from such collective fund for the lending of securities that is separate from any compensation of the Trustee hereunder, or any compensation of the collective fund trustee for the management of such collective fund.  The Trustee is authorized to invest in a collective fund which invests in The Bank of New York Mellon Corporation stock in accordance with the terms and conditions of the Department of Labor Prohibited Transaction Exemption 95-56 (the “Exemption”) granted to the Trustee and its affiliates and to use a cross-trading program in accordance with the Exemption.  ZionSolutions acknowledges receipt of the notice entitled “Cross-Trading Information”, a copy of which is attached to this Agreement as Exhibit C; and

15

(ix)          to make foreign investments, including investments to be maintained abroad; provided, however, that such authority is limited to those foreign jurisdictions in which the Trustee has selected a foreign custodian in accordance with Section 4.7 hereof.

Notwithstanding anything else in this Agreement to the contrary, including, without limitation, any specific or general power granted to the Trustee, including the power to invest in real property, no portion of the Fund shall be invested in real estate.  For this purpose, “real estate” includes, but is not limited to, real property, leaseholds or mineral interests.

(c)           ZionSolutions recognizes that settlements of transactions may be effected in trading and processing practices customary in the jurisdiction or market where the transaction occurs.  ZionSolutions acknowledges that this may, in certain circumstances, require the delivery of cash or securities (or other property) without the concurrent receipt of securities (or other property) or cash and, in such circumstances, ZionSolutions shall have sole responsibility for non-receipt of payment (or late payment) by the counterparty.

(d)           All investments must be sufficiently liquid to enable the Trust to fulfill the purpose of the Trust Agreement and to satisfy obligations as they become due as communicated in writing to the Trustee.  Nothing in this Section 4.2 shall be construed as requiring the Trustee to make any investigation as to when any of the Plants may be decommissioned or when obligations relating to such decommissioning may be expected to become due.

4.3          Prohibited Investments.  The Trustee shall assure that the assets of the Trusts are not invested or reinvested in the following Prohibited Investments:

(a)           Any securities or other obligations of EnergySolutions, Inc. or affiliates thereof, or their successors or assigns; or

(b)           Any securities or other obligations of any entity owning or operating one or more nuclear power plants; provided, however, that the foregoing restriction shall not prevent investments tied to market indices or other non-nuclear sector mutual funds; or

(c)           Any investment which would contravene any Future Orders in effect at the time such investment or reinvestment is made and previously furnished to the Trustee with reference to the Trust;

16

provided, however, that with respect to the securities and obligations prohibited under clauses (a) and (b), ZionSolutions provides a list of such securities and obligations and their issuer code and/or CUSIPs.

4.4          Management of Trusts.

The Trustee shall have the power to sell, exchange or otherwise dispose of all or any part of any Trust held hereunder, without prior application to or approval by or order of any court, upon such terms and in such manner and at such prices as the Trustee shall determine; to modify, renew, or extend, bonds, notes, or other obligations or any installment of principal thereof or any interest due thereon and to waive any defaults in the performance of the terms and conditions thereof; and to execute and deliver any and all assignments, bonds, or other instruments in connection with these powers, at such times, in such manner and upon such terms and conditions as the Trustee may be deemed expedient.  The Trustee’s determinations of manner of sales, terms, prices and the exercise of other powers granted herein, if reasonably made, are not to be questioned.

4.5          Extension of Obligations and Negotiation of Claims.  Subject to the limitations contained in Sections 4.2, 4.3 and 4.4 hereof, the Trustee shall have the power to renew or extend the time of payment of any obligation, secured or unsecured, payable to or by any Trust, for as long a period or periods of time and on such terms as it shall determine; and, subject to the approval of ZionSolutions (which shall not be unreasonably withheld or delayed), to adjust, settle, compromise, and arbitrate claims or demands in favor of or against the Trust, including claims for taxes, upon such terms as it deems advisable.

4.10        Right to Assign Disposal Capacity Assets.  The Trustee shall have the power to make a Qualified Assignment of the Disposal Services Agreement, as defined therein, and the power to make a Permitted Assignment of the Irrevocable Easement for Disposal Capacity, as defined therein.

4.11        Delegation of Ministerial Powers.  The Trustee shall have the power to delegate to other persons such ministerial powers and duties as it may deem to be advisable.

4.12        Discretion in Exercise of Powers.  The Trustee shall have the power to do any and all other acts which the Trustee shall deem proper to effectuate the powers specifically conferred upon it by the Trust Agreement and these Backup NDT Terms; provided, however, that this Section 4.12 shall not authorize the Trustee to do any act or participate in any transaction which would (a) contravene any provision of the Trust Agreement or these Backup NDT Terms; or (b) violate the terms and conditions of, or cause the Trust held under the Trust Agreement not to satisfy Applicable Regulatory Requirements.

CROSS-TRADING INFORMATION

As part of the Cross-Trading Program covered by the Department of Labor Prohibited Transaction Exemption (“PTE”) 95-56 for Mellon Bank, N.A. and its affiliates (“Mellon”), Mellon is to provide to ZionSolutions the following information:

I.             The Existence of the Cross-Trading Program

Mellon has developed and intends to utilize, wherever practicable, a Cross-Trading Program for Indexed Accounts and Large Accounts as those terms are defined in PTE 95-56.

II.            The “Triggering Events” Creating Cross-Trade Opportunities

In accordance with PTE 95-56, three “Triggering Events” may create opportunities for Cross-Trading transactions.  They are generally the following (see PTE 95-56 for more information):

1.                                      A change in the composition or weighting of the index by the independent organization creating and maintaining the index;

2.                                      A change in the overall level of investment in an Indexed Account as a result of investments and withdrawals on the Indexed Account’s opening date, where the Indexed Account is a bank collective fund, or on any relevant date for non-bank collective funds; provided, however, a change in an Indexed Account resulting from investments or withdrawals of assets of Mellon’s own plans (other than Mellon’s defined contributions plans under which participants may direct among various investment options, including Indexed Accounts) are excluded as a “Triggering Events”; or

3.                                      A recorded declaration by Mellon that an accumulation of cash in an Indexed Account attributable to interest or dividends on, and/or tender offers for portfolio securities equal to not more than .5% of the Indexed Account’s total value has occurred.

III.          The Pricing Mechanism Utilized for Securities Purchased or Sold

Securities will be valued at the current market value for the securities on the date of the crossing transaction.

Equity Securities - the current market value for the equity security will be the closing price on the day of trading as determined by an independent pricing service; unless the security was added to or deleted from an index after the close of trading, in which case the price will be the opening price for that security on the next business day after the announcement of the addition or deletion.

Debt Securities - the current market value of the debt security will be the price determined by Mellon as of the close of the day of trading according to the Securities and Exchange Commission’s Rule 17a-7(b)(4) under the Investment Company Act of 1940. Debt securities that are not reported securities or traded on an exchange, will be valued based on an average of the highest current independent bids and the lowest current independent offers on the day of cross trading.  Mellon will use reasonable inquiry to obtain such prices from at least three independent sources that are brokers or market makers.  If there are fewer than three independent sources to price a certain debt security, the closing price quotations will be obtained from all available sources.

IV.          The Allocation Method

Direct cross-trade opportunities will be allocated among potential buyers or sellers of debt or equity securities on a pro-rata basis.  With respect to equity securities, please note Mellon imposes a trivial dollar amount constraint to reduce excessive custody ticket charges to participating accounts.

V.            Other Procedures Implemented by Mellon for its Cross-Trading Practices

Mellon has developed certain internal operational procedures for cross-trading debt and equity securities.  These procedures are available upon request.
